Features to know about

Keeps Your Front End Clean: Hidden Base Plate with Removable Arms

When you’re not towing, this base plate practically disappears. The hidden design keeps the front of your vehicle looking clean and seamless, and the brackets don’t stick out past the bumper. The removable arms twist out easily so there’s nothing to bump your legs on, and receiver covers plug the openings to keep dirt and debris out for smooth connections next time you tow.

Quick Hookups Made Easy: Twist-Lock Arm Design

The removable arms use a simple twist-to-lock system that makes it easy to connect or disconnect your tow bar in seconds. Just insert, rotate until it locks, and secure with the pin. When you’re done towing, pull the pin, twist again, and remove. The setup is straightforward and secure—ideal for those who like a fast, no-fuss connection every time.

Built for Long Hauls: Steel Construction That Distributes Load Evenly

This base plate bolts directly to the chassis using the included hardware, spreading towing forces evenly to help protect your suspension from stress. The sturdy steel construction is powder coated to resist rust and corrosion, delivering reliability through long-distance travel and all kinds of weather.

Works with Your Favorite Tow Bars: Adapter-Friendly Compatibility

The sturdy lugs pair directly with Blue Ox tow bars for a solid, reliable link. If you already have a Roadmaster or Demco tow bar you like, adapters (RM-031, RM-031-5, or DM9523041, sold separately) make it easy to connect with this base plate. Integrated mounting points let you add an electrical connector bracket (sold separately) so your wiring stays neat and accessible up front.

Straightforward Setup: Bolt-On Install with No Welding Required

Installation is simple for anyone comfortable turning wrenches at home. The kit bolts directly to your chassis with included hardware—no welding needed. With an 18" distance between brackets and a 14" bracket height, you can plan your setup precisely and get a solid fit that’s ready for thousands of miles of dependable towing.

Product is a nice fit. I used this on a 2012 WRX. For install be prepared with decent drill bits, the vehicle chassis was pretty hard material where you had to drill for this one. I've already used it about 1200 miles of flat towing and it worked out great.

Installed using instructions - no problems - just a dull drill bit . . .

Glad I got it through eTrailer. Went to get it direct from blue ox. Said it would be 4-6 weeks to get it. Only took 3 days to get it over the estimated 5-7 days. All parts are accounted for. Including the installation instructions. Looking fwd to getting more things from them.

lways great to shop at etrailer, especially the tech experts. Royce did an awesome job with our order. Everything fit perfectly and the help video provided the guidance I needed.

We installed the baseplate on our 2023 Encore GX AWD as well as the light harness and breakaway switch. A couple of items were incorrect but Royce corrected the issues with no problems.

Thanks again etrailer!

Not really, I grew up in Chicago, basically 45+ years. I have been to Wrigley many times as a child and adult. We lived about 1 mile from the park. Going to see my mom who is 95 years old. Our favorite place to visit in Chicago is Navy Pier. We try to make a day of it. Thanks for asking! EdnJudy

Super high quality baseplate for towing by Blue Ox. Instructions, videos, shipping (one day!) and overall experience was awesome. A bit pricey but their quality and the additional support by E Trailer cannot be beat! BTW (E Trailer) the baseplate fits three different Jeep configurations but did not call out the Recon package. After looking at other brands which showed there's to fit the 3 variations AND the Recon, I figured it would fit and it DID. You should definitely upgrade to include the Recon Edition.

I looked into every brand/model available and this was the beefiest. There is cutting and trimming required on all brands, so why not get the strongest? If you're slightly handy with a toolbox, you can easily do the install yourself and save thousands.

The Blue Ox base plate for my 2015 Kia Soul is well manufactured and, with a little bit of mechanical skill, easy to install. It fit perfectly without issues. Brad from etrailer provides a step-by-step installation video that is outstanding and nicely guides through the process from beginning to end. I highly recommend this Blue Ox base plate from etrailer.

2019 Ford Ranger baseplate worked and fitted fine for me. 73 yrs old took me a couple hours but took many breaks. Younger could do it less than hour I'm sure.
Also works fine with my Blue Ox tow bar.

I installed this myself on a 2012 CR-V EXL AWD. The directions are straightforward. The system works very well and is easy to use.
Fair warning .. because the car is older, just about every clip that holds the grill and bumper in place broke when taking them off. Replacing all those clips with OEM parts is expensive!
BUT, that doesn't retract from the quality of the baseplate or it's use ability.
This is the third different Blue Ox baseplate system I have bought and installed and all of them were excellent!

Its been two years since installation of the Blue Ox Baseplate. Since then, Ive flat towed the CRV from NJ to FL and back three separate times with many other shorter trips in between. Paired with a Blue Ox Tow Bar, the system has worked flawlessly since installation.

Fits my 2013 mini cooper non turbo. Does take a few hours to install this Fit was good. The hardest part is removing the front bumper and reinstalling it. You do have to cut the lower bumper grill in three places take your time locating the exact spots for cuts. I have pulled Mini Cooper about seven thousand miles now with this Blue Ox and has worked great

Thanks for the detailed review Chris, and the pointers! This will be most helpful to others. What was your favorite stop in those 7,000 miles? Where did you go, what did you see?

by:

I got a used set for a great price and it worked out well. my only caution is that some of the holes in my 2008 2500 suburban had to be drilled to 9/16 due to misalignment with the tapped holes in the brackets. This minor adjustment made it all go togehter easily though. Be aware, you won't have tow hooks anymore if that is something you use a lot.

Follow up. Ive put about 8000 miles on the setup and its been great. A 34 ton suburban pulls nicely behind my Dutch star, and they dont have a steering lock so its nice not to have to retrieve keys when stopping for the night. I have used the safety cable attachment a few times for straight line pulls with a small shackle when working as a rally racing volunteer, its been fine but I wouldnt side pull on it.

by:
Well designed and solidly built base plate. Very good product support from Etrailer and Blue Ox.
The four 1/2 inch by 1 3/4 inch bolts are category 5 bolts. I had a bag full of identically sized bolts which were category 8. But I did not have any whizz nuts that were category 8 nuts so I stayed with the standard Blue Ox Hardware. We used POR 15 rust preventing paint at every location where we cut the steel or drilled holes. The distance from the center of the attachment tab assembly holes to the ground is 20 inches on our 2025 Wrangler Rubicon JLU with "Xtreme" 35 inch tire package. Easy five stars for Blue Ox and etrailer.

Great products from etrailer. The videos were very helpful as I was determined to do the install myself. I’m 72 years old and thought I could do it and I did with the help of my lovely assistant, my wife. The tip on running the taillight wiring through the frame rail was great. The one problem I had was that I was never able to unplug the taillights no matter how hard I tugged on them so I had my wife hold each light while I spliced in the diodes. Very happy with the Blue Ox products and the finished look on my Jeep. Thanks again etrailer.

It's a great system, it's on a 1998 Holiday Rambler Imperial, pulling a 2012 Ford F150 4x4. Last summer I pulled the truck for over 3000 miles without any problems, didn't feel like the truck was behind me. etrailer did me right on this set up.

Not for the impatient, but everything is provided. I had the front end of my Jetta all over the lawn. It’s definitely a 2 day job, but the instructions are thorough.

  • Can Blue Ox Base Plate Kit BX3615 be Used to Flat Tow 2013 Subaru WRX
    Hey Eric, yes the Blue Ox base plate kit part # BX3615 is a confirmed fit for your 2013 Subaru Impreza WRX and would work great with the Blue Ox Acclaim part # BX4330 that you referenced. In addition to the base plates, you will also need a compatible tow bar, safety cables, lighting, and supplemental braking to flat tow your vehicle. One of the most popular compatible tow bars is the Blue Ox Avail # BX7420 which comes with safety cables. The coiled design helps keep the cables off of...

  • Recommended Complete Flat Tow System For 2013 Subaru XV Crosstrek With Automatic Transmission
    Your 2013 Subaru Crosstrek XV automatic transmission can be flat towed if you don't have a CVT model which cannot and I'd be happy to help with a complete system for you. For your base plates, I recommend the Blue Ox Base Plate Kit - Removable Arms # BX3615. For this install you will want to use Loctite Threadlocker # LT37420. This can be used seamlessly with the Blue Ox Aladdin Tow Bar that you referenced (which is discontinued) or the Blue Ox Alpha Tow Bar # BX7380. That will come...

  • Recommended Components For Flat-Towing 2013 Subaru XV Crosstrek AWD
    On page 9-15 of the owner's manual I found information about towing your Crosstrek. The manual does say that the best method is to carry the vehicle on a flatbed. It does not specifically say flat-towing is not permitted, so I recommend checking with your dealership to make sure you follow any restrictions for your Crosstrek. The base plates I recommend are part # BX3615. This has removable arms so less of the base plate is visible when you are not towing. For a tow bar I recommend...
